Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have tried everything, I even Installed Microsoft Office Removal tool but that did'nt worked either, So i went to Task Manager and Ended Oneclickoffice Services and then it worked, I am a Local tech here i have done Bachelors in Computer Science, This issue occurred in my 30 to 40 Customers and i did the same thing to all of them in soe cases i did it couple of time but it worked everytime, I am unaware about this cause but it seems installation somehow stuck and by stopping the Oneclick Process and Install Office then again worked for me.
This answer is on the right track but is incomplete. The service in question is named "ClickToRunSvc" and its description is "Microsoft Office Click-to-Run Service." You do need to stop it, but you must restart it if it doesn't do so itself. It this service remains stopped, the installation will not proceed.
